How is nitrogen metabolism in the prokaryotes vital to other organisms? given the roles of bacteria in the nitrogen cycle, how w
Murljashka [212]
Metabolizing nitrogen in prokaryotes is very important to other organisms since these prokaryotes are able to convert ammonium in the soil to nitrate and, then, the denitrifying bacteria could use the nitrate produced instead of using oxygen in their metabolism in order to release nitrogen molecules. by the denitrification process, thus completing the nitrogen cycle. Without the nitrogen metabolism in prokaryotes, the nitrogen in the atmosphere could not be used or utilized to synthesize essential organic compounds that are needed by other organisms. It is only the prokaryotes that has the ability fixing nitrogen or can do the process of nitrogen fixation.

riadik2000 [5.3K]

Answer:

A) histone coding genes

Explanation:

Histones are the proteins involved in the packing of DNA in eukaryotes. They are positively charged proteins and are not found in bacteria. To analyze the evolutionary relationship in a gene between eukaryotes and bacteria, one must choose the gene present in both of them. The tRNA, rRNA and hexokinase encoding genes are common to both bacteria and eukaryotes. Therefore, one of these genes may be chosen for the study. However, histone encoding genes are not present in the genomes of bacteria. Therefore, the study of the histone encoding gene would not be useful for the mentioned purpose.
